Compared to people of normal weight, obese people have a 50% to 100% increased risk of dying prematurely. Obese people are at an increased risk of developing:

• Diabetes (type 2)
• Joint problems (e.g., arthritis)
• High blood pressure
• Heart disease
• Gallbladder problems
• Certain types of cancer (breast, uterine, colon)
• Digestive disorders 
• Breathing difficulties (e.g., sleep apnoea, asthma)
• Psychological problems such as depression
• Problems with fertility and pregnancy
• Urinary Incontinence
• Depression, anxiety, and social isolation
  

Aside from the health risks that obesity poses, day-to-day living can become difficult and frustrating:

• Normal tasks can become harder when you are obese as movement is restricted
• Simple tasks can see you tire quickly and become short of breath
• Public transport, car and aeroplane seats, theme park rides, chairs in restaurants, and public phone booths can become too small
• Maintaining personal hygiene may become more challenging
